6baa2c4420 * Get rid of identifiers since they are redundant now. This greatly
simplifies stuff.

* The format of Nix expressions and the database schema changed
  because of this, so it's best to delete old Nix installations.

b9f4942bd2 * string -> Path. 2003-10-07 14:37:41 +00:00
Eelco Dolstra
5d4171f7fb * Synchronise terminology with the ICSE paper (e.g., slice -> closure,
fstate -> Nix expression).
* Fix src/test.cc.

4193d62e08 * Nix now respects $TMPDIR for the creation of temporary build directories.
* Retry creation of a temporary directory (with a different name) in the 
  case of EEXIST.

1c7d6bf5fc * Removed references to char_traits so that boost/format also works on
GCC 2.95.

803a924b77 * Make nicer dot graphs. Also show the inner structure of slices. 2003-09-03 14:49:58 +00:00

c0bbed0959 * Factored out dot graph generation into a separate file. 2003-09-03 11:20:18 +00:00
Eelco Dolstra
0d2bc68681 * Do not show the output of the builder unless the verbosity is at
least at debug level (-vvv).  The output is still appended to the 
  build log in /nix/var/log/nix.

b018517314 * Do not try to remove write permission from symlinks, since chmod()
follows symlinks.  (Note that the permissions on symlinks are
  ignored anyway.)

31be53cd0a * Fix the atrocious (exponential? factorial?) time complexity in
`nix --query --requisites'.

a88144215c * Remove write permission from output paths after they have been built.
* Point $HOME to a non-existing path when building to prevent certain tools (such as 
  wget) from falling back on /etc/passwd to locate the home directory (which we 
  don't want them to look at since it's not declared as an input).

956801fcc2 * Use maps and sets in the FState data type. This ensures normalisation of
slices and derivations w.r.t. order of paths, slice elements, etc.
2003-08-20 14:11:40 +00:00
Eelco Dolstra
624c48260f * Change the abstract syntax of slices. It used to be that ids were used as
keys to reference slice elements, e.g.,

    Slice(["1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["8c99..."]), ...])

  This was wrong, since ids represent contents, not locations.  Therefore we
  now have:

    Slice(["/nix/store/1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["/nix/store/8c99-..."]), ...])

* Fix a bug in the computation of slice closures that could cause slice
  elements to be duplicated.

Eelco Dolstra
ed0db2e0d8 * Fixed a serious bug in the computation of slices. Sometimes the slices
would not be properly closed under the path reference relation.

1472cc4825 * Pipe /dev/null into stdin. 2003-08-19 13:07:38 +00:00

2de8504791 * Delete the temporary directories of failed builds by default, and an
option `--keep-failed' to override this behaviour.

Eelco Dolstra
31e4aa6439 * Allow lists in package bindings, e.g.,
("srcs", [Relative("foo/bar.c"), Relative("foo/baz.h")])

  The result is an environment variable that contains the path names of the
  inputs separated by spaces (so this is not safe for values containing
  spaces).

ebbb6ce578 * Most shells initialise PATH to some default (/bin:/usr/bin:...)
when PATH is not set.  We don't want this, so fill it in with
  some dummy value.

96c7b98bf0 * Argument support in Fix. Arguments can be passed through the
builder using the `args' binding:

  ("args", ["bla", True, IncludeFix("aterm/aterm.fix")])

  Note that packages can also be declared as inputs by specifying them
  in the argument list.

555347744d * Derivation expressions now can specify arguments to be passed to the
builder.  Note that this unfortunately causes all Fix-computed
  hashes to change.

163db7367f * Fix can now read expressions from stdin (by saying `fix -'). 2003-08-15 09:21:19 +00:00

dc0ef2ca98 * Detect infinite loops using blackholing. 2003-08-14 12:37:31 +00:00

5cde23f869 * Function() takes a list of formals. 2003-08-14 09:49:31 +00:00

0a2de7f543 * Lam -> Function. Doh! 2003-08-14 09:29:07 +00:00
Eelco Dolstra
c602930e08 * deletePath(): some operating systems (e.g., Mac OS X) don't like it
when we delete entries from a directory while we are reading it.
  So read the directory into memory, then delete its contents.
2003-08-08 14:55:56 +00:00
Eelco Dolstra
236eb59293 * Allow locks on paths to be acquired recursively (that is, if the
process is already holding a lock on a path, it may acquire the lock
  again without blocking or failing).  (This might be dangerous, not
  sure).  Necessary for fast builds to work.
2003-08-06 09:34:04 +00:00
Eelco Dolstra
720f06e3b0 * A flag `--flat' to just compute the MD5 checksum of the contents of
a regular file.  I.e., `nix-hash --flat' is equivalent to the
  coreutils `md5sum' command (which doesn't exist on all systems).
2003-08-06 09:06:32 +00:00

37483672d4 * App -> Call.
* Allow booleans in package environment bindings (True maps to "1",
  False maps to "").

17f05dba77 * Allow the top-level expression to be a list of expressions that
normalise to Nix expression.

d6b6b2d3a8 * Delete obstructed paths prior to building. 2003-08-05 09:47:20 +00:00

d2e963f7a3 * Path locking in addToStore() and expandPath(). 2003-08-04 07:09:36 +00:00
Eelco Dolstra
c95b4ad290 * In normaliseFState(), wrap registration of the output paths and the
normal form in a single transaction to ensure that if we crash,
  either everything is registered or nothing is.  This is for
  recoverability: unregistered paths in the store can be deleted
  arbitrarily, while registered paths can only be deleted by running
  the garbage collector.

d99d04e644 * Defensive programming against POSIX locking idiocy.
* Simplified realiseSlice().
2003-08-01 15:06:23 +00:00
Eelco Dolstra
545145cd58 * normaliseFState() now locks all output paths prior to building, thus
ensuring that simultaneous invocations of Nix don't clobber
  each other's  builds.

* Fixed a bug in `make install'.

9df93f30bd * Don't use substitutes in addToStore(). 2003-08-01 09:01:51 +00:00

06434072e7 * Put the database verifier in a transaction. 2003-07-31 19:49:11 +00:00
Eelco Dolstra
06d3d7355d * Enclose most operations that update the database in transactions.
* Open all database tables (Db objects) at initialisation time, not
  every time they are used.  This is necessary because tables have to
  outlive all transactions that refer to them.

177a7782ae * Use a more reasonable log file size (256 KB instead of 10 MB).
* Checkpoint on exit.

Eelco Dolstra
4a013962bd * Started using Berkeley DB environments. This is necessary for
transaction support (but we don't actually use transactions yet).

83075304e5 * Don't make the builder executable. 2003-07-30 09:49:47 +00:00
Eelco Dolstra
8846465934 * Get garbage collection and cache population to work *properly*.
Renamed `fstateRefs' to `fstateRequisites'.  The semantics of this
  function is that it returns a list of all paths necessary to realise
  a given expression.  For a derive expression, this is the union of
  requisites of the inputs; for a slice expression, it is the path of
  each element in the slice.  Also included are the paths of the
  expressions themselves.  Optionally, one can also include the
  requisites of successor expressions (to recycle intermediate
  results).

* `nix-switch' now distinguishes between an expression and its normal
  form.  Usually, only the normal form is registered as a root of the
  garbage collector.  With the `--source-root' flag, it will also
  register the original expression as a root.

* `nix-collect-garbage' now has a flag `--keep-successors' which
  causes successors not to be included in the list of garbage paths.

* `nix-collect-garbage' now has a flag `--invert' which will print all
  paths that should *not* be garbage collected.

dc14a3de46 * Nicer dot graphs. 2003-07-29 10:53:27 +00:00
Eelco Dolstra
79ba0431db * `fstateRefs' now works on derive expressions as well. TODO: make
this more efficient.
* A flag `-n' in 'nix --query' to normalise the argument.  Default is
  not to normalise.
2003-07-29 10:43:12 +00:00
Eelco Dolstra
5acb45446e * Let `nix --install' print out the id of the normal form.
* Some minor refactoring.
2003-07-29 09:45:03 +00:00
Eelco Dolstra
949c4fa1a8 * `nix --help'.
* `nix --query --graph' to print a dot dependency graph of derive
  expressions.
